ROLLER GUIDE 'ronrLAr CUTTING AND BUILDING mA'CnINns.

Application filed mm 20, 1924. Serial- Na'm w.

To all whom it may concern:

-Be it known that I, JosErH E. PaBnAUL'r,

a citizen of the United States, and resident of \Vatertown, in thecounty of Middlesex 6 and State of Massachusetts, have invented certainnew and useful Improvements in Roller Guides for Flap Cutting andBuilding- Machines, of which the following is a specification.

proved roller uide designed for use in connection with dap cutting andbuilding machines such as disclosed in an application filed by me in theUnited States Patent Oflice on the 26th day of June, 1922, Serial In theuse of such a machine, a traveling sheet of friction fabric is severedinto a plurality of relativel narrow strips or bands, which are de ectedby horizontal guides into different rizontal planes, whereafter they areali ed in grou s b vertical guides, theban s or strips 0 eac group beingsuperrimposed and pressed together by rollers to form laminated bands ortire flap strips. 4

In the use of the machine shown in said application, there developed attimes a tendenc of the bands, which are' of friction fabric and stickyor tacky, to curl at the edges or wrinkle, which would result in suchcurls or wrinkles bein pressed down, resulting in a defective a and thepresent invention aims to provide means which will guard against suchoccurence.

The said invention comprises the novel construction hereinafterdescribed and defined by the appended claims.

In order that the invention may be better understood, reference is madeto the accompanying drawings, in which Figure 1 is a perspective View,largely of a diagrammatic nature, showing two strips traveling-around orover the several guides, and being united by the presser rollers, theframe and supporting parts being omitted for clearness of illustrationsFig. 2 is a plan view of oneset of glides.

Fig. 3 is a section on line 33 of ig. 2.

Referring by reference characters to this drawing, the numerals 1designate the vertical guides correspondin to the guides 16 and '17 ofmy aforesaid application, by

My present invention relates to an imwhich the strips or bands 2 and,2", which have been produced by the slitting up of the sheet, aredeflected-into vertical ahgnment one above the other for the pur ose ofsubsequently joining them face to acc to' form the composite sheetby-th'e presser rollers 3 and 4. Between the vertical guides 1 and thepresser rollers 3 and 4 are interposed upper and lower pairs ofhorizontal uide rol s 5 and 6, the rolls of each pair ing spaced apartto permit the passage of the friction fabric t erebetween, whereby thefabric is properly guided to and between the uniting rollers 3 and 4.Due to the fact that the fabric is given a quarter turn in passing fromthe vertical ides 1 to. the uniting rollers, I have founft hat by theuse of horizontal guides such as disclosed at 19, 19 and 19 in myaforesaid application there is likelihood at times of the curlin o theedges of the fabric and the possibility of wrinkling or distortion, andto avoid this I provide the special guide roller mechanism which willnow be particularly described. This comprises up er and lower dividedrollers 5 and 5", an 6 and 6, res ectively, which are journaled onhorizonta shafts 7 and 8 carried by frame members 9and 10. The rollers 5and 6 are spaced apart a distance just sufficient to admit the fabric,so as to bear on the o posite faces thereof, while the rollers 5 and 6are spaced further apart to allow the free passage of the remainingportion of the fabric. The supporting bracket or standard 10, is rovidedwith a horizontal recess 10" in a ignment with the space between therollers, and in this recess is journaled a roller 11 the peripher ofwh1ch contacts with the edges of the ro lers 5 and 5, enclosing thespace, and serves as an anti-friction gulde for the ed 0 of the strip.Preferably, the roller 11 1s 95 projected slightly beyond the face ofthe supporting bracket or standard, and the corf responding edges of therollers and 6" are rebated, as indicated at 5 and 6", to form a grooveinto which theedge of the roller 11 projects.

Having thus described my invention, what I claim 1s 1. Fabric stripguiding means for the urose described, comprising a pair of ro lers 105ournaled to rotate about parallel axes, and

a roller journaled to rotate about an axis perpendicular to said axesand having its perlphery closing the space between the parallel rollers,said last named rollers being spaced apart a distance corresponding tothe fabric strip,whereby the rollers contact with o posit-e faces of thefabric and any wrinkling of the same o'r curling of its guiding edge isprevented.

2. Strip guiding means for the purpose described, comprising a pair ofparallel shafts, cylindrical rollersjournaled. thereon adjacent one endthereof, with a space between corresponding tothe thickness of thestrip, cylindrical rollers journaled on the remaining portion of theshafts, and of less diameter than the, first mentioned pair to provide awider space between, and an anti- 7 friction: guide cooperating w th,the adjacent portions of the first mentioned pair of rollers at theouter ends thereof.

3. Strip guiding means for the purpose described, comprising a pair ofparallel shafts, cylindrical rollers journaled thereon adjacent one endthereof, with a space between corresponding to the thickness of thestrip, cylindrical rollers journaled on the remaining portion of theshafts, and of less diameter than the first mentioned pair to provide awider space between, and a roller journaled to rotate about an axisperpendic- -ular to said shafts, and having its periphery adjacentto andclosing the space between said first mentioned rollers at the outer endthereof. In testimony whereof, I afiix my signature,
